Answer:

9

Step-by-step explanation:

f(x)=2x^2-3x+7

To find the value of the function at f(2), you just replace x with 2:

f(2)=2(2)^2-3(2)+7

f(2)=2(4)-3(2)+7

This is as far as she got. She is doing great so far.

f(2)=8-6+7

f(2)=2+7

f(2)=9

The value of the function at x=2 is 9.

<h3>Answer:</h3>

\large\boxed{\text{f}(2)=9}}

<h3>Step-by-step explanation:</h3>

In this question, we're solving for the function when x = 2

What this means is that you would plug the number 2 in every "x" value.

When you plug in the 2's, your equation should look like this:

\text{f}(2)=2(2)^2-3(2)+7

Now, you would solve to get your answer.

\text{f}(2)=2(2)^2-3(2)+7\\\\\text{You would carry over the exponent to the number 2 in the parenthesis,}\\\text{That would be equivalent to 2 * 2, making it 4.}\\\\\text{f}(2)}=2(4)-3(2)+7\\\\\text{f}(2)}=8-3(2)+7\\\\\text{f}(2)}=8-6+7\\\\\text{f}(2)}=9

When you're done solving, you should get 9.

This means that f(2) = 9

Find the equation of the line shown.<br> Pls help I’m so confused
Dahasolnce [82]

Answer:

the equation for a line is y=MX+b

m= slope(rise/run)

x=variable

b= y intercept

you would find the slope by looking at the rise over run which are both 1 and the line is negative so the slope would be negative one

you would find b by looking at where the y intercept is (y when x is zero) which is 9

y= -x+9

hope that helped
